This particular tape was recorded at EP speed with linear stereo sound. The sound was recorded traditionally using the audio RCA jacks on the VCR. This result is the best that can be achieved compared to traditional "hardware decoded" playback using standard composite video capture cards, dongles, and other consumer capture devices. The software decoding method bypasses a portion of analog circuitry in a typical VCR used to demodulate and decode the raw RF tape signal to composite video or s-video. The end result is a cleaner and sharper picture because of less analog noise and distortion, and more video bandwidth is preserved and captured.
